Daim Ntawv Qhia Sib Piv Txog Kev Ua Haujlwm Zoo ntawm Membrane vs Cryogenic Air Separation

Cov Ntsiab Lus: Yuav Ua Li Cas Membrane thiab Cryogenic Tech Ua Haujlwm Tiag

Thaum peb tham txog kev sib piv cov thev naus laus zis sib cais cua, peb tab tom saib ob lub tswv yim sib txawv ntawm physics: kev lim dej yooj yim piv rau cov thermodynamics nyuaj. Ntawm Xiamen Xingchangjia, peb pom cov neeg siv khoom muaj teeb meem nrog qhov kev xaiv no txhua hnub. Kev nkag siab txog cov txheej txheem tseem ceeb yog thawj kauj ruam hauv kev txiav txim siab seb qhov kev teeb tsa membrane vs cryogenic oxygen tsim khoom haum rau koj qhov chaw. Koj tsis yog tsuas yog yuav lub tshuab xwb; koj tab tom xaiv cov txheej txheem uas dictates koj cov nqi hluav taws xob, lub sijhawm txij nkawm, thiab cov roj huv rau kaum xyoo tom ntej.

Kev Sib Cais Daim Ntawv: Kev Yooj Yim Hauv Kev Ua Haujlwm

Yog tias koj xav tau lub kaw lus uas zoo li "plug thiab ua si," polymeric membranekev sib cais cuafeem ntau yog cov lus teb. Lub tswv yim ntawm no yooj yim heev. Peb siv cov fibers hollow semi-permeable - xav txog lawv zoo li cov straws me me - bundled hauv lub cartridge cylindrical.

Thaum peb yuam cua compressed rau hauv cov fibers no, lub physics ntawm kev xaiv permeation yuav siv. "Ceev" cov pa roj xws li oxygen, carbon dioxide, thiab cov dej pa permeate los ntawm cov phab ntsa membrane sai sai thiab raug vented tawm ntawm qhov siab qis. "Qeeb" cov pa roj, feem ntau nitrogen, ntws mus rau hauv nruab nrab ntawm cov fiber mus rau lwm qhov kawg raws li cov khoom roj.

Vim li cas peb thiaj nyiam nws:

• Ob Peb Qhov Chaw Txav Mus Los: Sib nrug ntawm lub compressor, tsis muaj ntau yam kev ua haujlwm kho tshuab.
